The electronic structure of the lithium atom in a strong magnetic field 0{<=}{gamma}{<=}10 is investigated. Our computational approach is a full configuration interaction method based on a set of anisotropic Gaussian orbitals that is nonlinearly optimized for each field strength. Accurate results for the total energies and one-electron ionization energies for the ground and several excited states for each of the symmetries {sup 2}0{sup +}, {sup 2}(-1){sup +}, {sup 4}(-1){sup +}, {sup 4}(-1){sup -}, {sup 2}(-2){sup +}, {sup 4}(-2){sup +}, and {sup 4}(-3){sup +} are presented. The behavior of these energies as a function of the field strength is discussed and classified. Transition wavelengths for linear and circular polarized transitions are presented as well.
